I was just putting in a seed order for my Chicken Garden, a small garden completely for my chickens. I just wanted to make sure the following would be alright for them to eat: Calendula Rainbow Swiss Chard Carrots Buttercrunch Lettuce Turnip Greens Collard Vates (Collard Greens?) Tomatoes Any advice is appreciated! Is there anything not listed that sould be in the garden? Thanks!
